MATTRESS-ROLL FORMING AND STITCHING MACHINE.

Application filed August 17, 1926. Serial 110.129,!300.

My invention relates to improvements in roll forming and stitching machines for forming roll edges upon mattresses and the like. Reference is hereby made to my former Patents Number 1,503,351, issued July 29, 1924; Number 1,511,403, issued 'Oct. 14, 1924; and Number 1,519,299, issued Dec. 16, 1924, all of which disclose machines of the general type over which the present invention is an improvement.

The primary object of my invention is to provide an improved machine for forming and stitching roll edges upon mattresses.

Another object is't-o provide an improved machine provided with improved means for forming a roll and for holding said roll during the stitching thereof. a

A further object is to provide improved means operating in conjunction with roll forming mechanism for compressing the roll during the stitching operation and fonstrip ping the formed roll from the forming means when the forming means are withdrawn from the mattress.

Another object is to provide an im roved machine. of the character describe provided with improved stitch forming-mechanism adapted to obtain a more smooth and regular stitch formed from a single thread firmly knotted about the material embraced within each stitch to lock the same.

Another object is to provide improved means for paying out and taking up the thread during the forming of each stitch to prevent the breaking of the thread and to obtain firm regular stitching.

1 A further object is to provide an improved -me chan'ism including improved means for regulating the length of thread paid out for forming each stitch.

' Another object is to provide an improved mechanism operating in connection with the forming and stitching mechanism for moving the machine intermittently between stitches and for positively locking the mov ing mechanism and the machine against furtheir movement after each successive move ment to obtain a uniform spacing of stitches.

A further object is to provide an improved intermittent moving mechanism for a ma chine of the character described which may be easily and quickly set to form long or short'stitches as desired.

A further object is to provide an improved machine provided with improved means for holding the mattress against movement during the forward movement of the machine to obtain a regular roll and uniform stitching.

Another object is to provide a machine of the character having improved means for varying the speed of the machine while the same is being moved around the corners of a work supporting table.

A still further object is to provide an improved machine of the character described l'iaving improved and simplified construction whereby the moving mechanism is coordinated to give increased efficiency and to produce an improved mattress.

I accomplish these and other objects by means of the improved machine disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar'parts' throughout said specifications and drawings and in which,

Fig. 1 1s a side elevatlon of my improved -mattress roll forming and stitching machine as mounted upon the edgeof a work supporting table, the adjacent head cover being re- .moved.

Fig. 2 is a rear elevation of the machine as shown in Fig. 1.

Fig; 3 is a sectional detail showing the means whereby the body of the machine is adjusted vertically with respect to its carriage. i

Fig. 4 is a side elevation of the machine head with the cover removed, the figure being drawn upon a larger scale.

Figs. 5 and 6 are side elevations of the machine head with the cover and cam removed and showing various positions of the roll forming mechanism.
